**Abstract:**

In this paper we investigate the ion-ball screening model (model (I)), which is focused on the screening electrostatic potential per electron under the Wigner-Seitz approximation and the

*Q*-value correction. By considering the changes of the Coulomb free energy and the effects of strong electron screening (SES) on the

*Q*-value and the Coulomb chemical potential, we discuss the linear-response screening model (model (II)). We also analyze the influence of the SES on the

*Q*-value, the electron chemical potential and electron energy, and shell and pair effects. It is found that the antineutrino energy loss rate increases by two orders of magnitude (e.g., the SES enhancement factor can get to 651.9 for model (II)), due to the SES effect.

**Abstract:**

The deducing Langevin equation has been applied to investigate the isoscalar giant monopole resonance in our previous work. In this work, the framework is extended to study the isovector giant dipole resonance (IVGDR). The potential well in the IVGDR is calculated by separating the neutron and proton densities based on the Hartree-Fock ground state. Then the Langevin equation is solved self-consistently, resulting in the centroid energy of the IVGDR without width. It is found that the symmetry energy around the density 0.02 fm

^{−3}contribute the most to the potential well in the IVGDR. Comparing to the updated experimental data of IVGDR energies in the spherical nuclei, the calculations within 37 sets of Skyrme functionals suggest the symmetry energy from 8.13 to 9.54 MeV at density 0.02 fm

^{−3}.

Computation of products of phase space factors and nuclear matrix elements for the double beta decay

**Abstract:**

The nuclear matrix elements (NME) and phase space factors (PSF) entering the half-life formulas of the double-beta decay (DBD) process are two key quantities whose accurate computation still represents a challenge. In this paper we propose a new approach of calculating them, namely to compute directly their product as an unique formula. This procedure allows a more coherent treatment of the nuclear approximations and input parameters appearing in both quantities and avoids possible confusion in interpreting the DBD data due to different individual expressions adopted for PSF and NME (and consequently their reporting in different units) by different authors. Our calculations are performed for both two neutrino (

**Abstract:**

The newly observed isomer and the ground-state band in odd-

*Z*neutron-rich rare-earth nucleus

^{163}Eu are investigated by using the cranked shell model (CSM) with pairing treated by a particle-number conserving (PNC) method. This is the first time the detailed theoretical investigations are performed on the observed 964(1) keV isomer and the ground-state rotational band in

^{163}Eu. The experimental data are reproduced very well by the theoretical results. The configuration of the 964(1) keV isomer is assigned as the three-particle

^{163}Eu. Due to its significant effect on the nuclear mean field, the high-order

^{162}Sm and

^{164}Gd, there is a 10%~15% increase in

^{163}Eu. This is explained by the pairing reduction due to the blocking of the nucleon on the proton

^{163}Eu.

The production cross sections of the exotic neutron-deficient nuclei in multinucleon transfer reactions are much larger than those measured in the fragmentation and fusion-evaporation reactions. Several new neutron-deficient nuclei can be produced in

^{112}Cd+Sn reaction. The corresponding production cross sections for the new neutron-deficient nuclei,

**Abstract:**

Within the framework of Dyson-Schwinger equations and by means of Multiple Reflection Expansion, we study the finite volume effects on the chiral phase transition in a sphere, especially discuss its influence on the location of the possible critical end point (CEP). According to our calculations, when we take the sphere instead of cube as a research, the influence of finite volume effects on phase transition is not as significant as previously calculated. For instance, as the radius of spherical volume decreases from infinite to 2 fm, at zero chemical potential and finite temperature, the critical temperature
